Brief Introduction:
MHHPA is soluble in benzene and acetone,hygroscopicity.In addition to the general performance of methyl THPA,It is colorless transparent liquid. It will not change color if added accelerator. The epoxy curing material is colorless and transparent, with good heat resistance. This epoxy curing material has excellent mechanical behavior and electrical property.
MHHPA is heating-solidification type acid anhydride solidifying agent, mainly used in dipping of coil of electric apparatus, casting of electric parts and sealing of semiconductor.
